Hidden Achievements

[Celtic]

I'm trying to get all those achievements. Today i was going for 'Be dominated in a game you've watched'. So I planned a friendly with my strongest friend. Put up an illegal formation with all my players out of position. This was the result:

But I still didn't get the trophee. I thought 'dominated' was 5 goals or more difference? Can someone tell me why I haven't got my trophee?

I can.

Has to be in an official match.
